White Blood Cells Connective Tissue
3,064 words... site Connective tissues have three main elements: ground substance, fibers, & cells. Ground substances make up the extracellular matrix. (Note: that the term matrix indicates the ground substance. ) Ground Substance - is an amorphous (unstructured) material that fills the space between the cells & contains the fibers. It is composed of interstitial fluid, cell adhesion proteins, & proteoglycans. Cell adhesion proteins, a group that includes fibronectin & lamina, sever mainly as a connective ...

Mycobacterium Tuberculosis Rheumatoid Arthritis
1,983 wordsInflammation is the bodies normal response to injured tissues, although it can sometimes lead to further tissue damage. It was first described around 30 BC by Celsius, as tumour (swelling), rumor (redness), calor (heat) and door (pain); although excess secretion and loss of function are now commonly added. Inflammation is a response which has evolved to try and put things right in a damaged tissue, for example the pain and loss of function allow the tissue to heal easier whilst the heat and redn...

The Eye And Laser Surgery
1,557 words... pascal pulse of 250 is very long compared to other lasers. The discharge is build up in three phases: 1) X-ray pre-ionisation provides a homogeneous distribution of electrons in the discharge area. 2) A high voltage pre-pulse with a very fast rise time multiplies these electrons in an avalanche process, providing a homogeneous ignition of the discharge. Finally the main pulse gives the high current at moderate voltage to create the laser output. The energy per pulse is 1 Joule. With a repeti...

Benign Tumors Malignant Tumors
1,817 wordsSarcoma Sarcoma, highly malignant tumor arising in connective- and muscle-cell tissue. It is the result of oncogenes (the cancer causing genes of some viruses) and proto-oncogenes (cancer causing genes in human cells). It may affect bone, cartilage, blood vessels, lymph nodes, and skin. Soft tissue sarcomas are malignant (cancerous) tumors that can develop from fat, muscle, nerve, joint, blood vessel, or deep skin tissues. They can develop in any part of the body. Half of them develop in the arm...

Soft Tissue Radiation Therapy
1,861 words... in which they developed DNA expression profiles that can be used to accurately diagnose nine soft-tissue sarcoma subtypes, representing approximately 70 % of these cancers. To develop such profiles, researchers use a gene-expression microarray, or "gene chip. " The chip contains thousands of known gene samples printed onto a quartz wafer in tiny dots. When a gene in a study cell matches one on the chip, it binds tightly, like two pieces of a puzzle. The cellular material causes the matched g...

Uv Light Respiratory System
1,069 wordsPrint Carbon CARBON process, The Print fading was a common occurrence in the earliest days of photography, and several people sought to address themselves to this problem. In the mid 1850 s some began to experiment with carbon, and in 1864 Joseph Wilson Swan perfected the process, which he also patented. Prints made using this process came in any colour, and were permanent. The sensitizing solution consisted of a mixture of carbon, gelatin, the colouring material, and potassium bichromate. Once ...

Parent Child Relationship Parkinsons Disease
1,668 wordsIs the transplantation of neutral tissue considered an ethical procedure? The transplantation of human fetal neural tissue into the brains of humans suffering from progressive neurodegenerative disorders is one of the hottest arguments currently being debated. Fetal neural tissue is being used as a possible treatment for some diseases. The treatment and possible cure for many of these diseases falls upon the successful transplantation of fetal neural tissue from the brain, spinal chord and perip...

Red Blood Cells Pulmonary Artery
6,589 wordsForwards and backwards to the right and are at the same level of the fifth to eight dorsal vertebrae. The apex of the heart points downwards and forwards to the left and corresponds to the space between the fifth and sixth ribs. However, in thin people, the hearts apex may be pointing more downwards than to the left. Its atrial border corresponds to a line drawn across the sternum on a level with the upper border of the third costal cartilage. Its apex corresponds to a line drawn across the lowe...
